Unworldly little movie no doubt made for doctors to show other doctors case examples of people suffering from schizophrenia.
While some people have called this a freak show, just remember this was made for doctors, so yes, this does have some value. Interesting how some of the patients had crude masks, like in Zorro or some sort of misunderstood superhero.
Also worth noting is that this movie WAS made in the 1930s, so a lot about schizophrenia and psychiatry wasnt known at the time, (and heck, Tom Cruise, even Tom Cruises Mom wasnt around to diss it). I wonder how many of these symptoms could be helped by modern drugs today.
